- Starting on finding pitch of notes and accidentals not in key sigs. Requires a little more work on ledgers.
- Finding/grouping all ledgers between staves and connecting them to stems/staves/bars, but not yet finding ledgers at top and bottom of line.
- Finding all ledgers. It looks like some ledgers are duplicated and should be removed (todo).
- Starting to match accidentals to notes. An accidental (not in a key signature) will reference its primary note, but multiple notes in a bar may reference an accidental.
- That will be easier after I've found natural note pitches. Starting that first.

Or better yet, going out.
